Fedora directory users - Mar 2006 - failed to install a local copy of ds10.jar (after upgrade to 1.0.2)

Hello.
I have upgraded my directory to 1.0.2.
I can  startconsole but when I click on Directory Server node, I get
the following error message:

"Installing server components downloading ds10.jar (0k)"

After a while it says:

"Failed to install a local copy of ds10.jar or one of its supporting 
files:
can not connect to http://localhost:3060"

What is the problem?

Operating system information is: fedora core 4, 2.6.15-1.1831_FC4smp
java  -version is: 1.5.0_06
I used the below link to install java 1.5 to get  a solution for the problem :

But it did not work.

Thanks for your help.
